Description

Lenses combined with soft elastomer

This creation is about a combination structure of lenses and elastomers that uses roughened surfaces to increase the bite force.

In order to increase the tightness and comfort when wearing common spectacle lenses, a protective pad body is combined with the upper edge of the lens to achieve the above-mentioned tightness and comfort.

For example, there is the new patent case No. M597878 "TPR glasses structure" announced on July 1, 2020. It is disclosed that: a nose bridge is formed upward at the middle lower edge of the single-piece lens, and pivot joints are formed on both sides of the lens, so that the pad body is made of thermoplastic rubber elastomer [Thermoplastic Rubber, TPR]. , an upper frame is formed at the upper end of the pad body corresponding to the upper edge of the lens, and a nose pad is formed at the lower end corresponding to the bridge of the nose. The upper frame part and the nose pad are connected with a connecting section, and the pad body is integrally formed and shot out of the package. Cover the lens, so that the upper frame is combined with the upper edge of the lens, and the nose pad is combined with the bridge of the nose, so that the pivoting part of the front edge of the temple is pivotally combined with the pivoting part of the lens; thereby, the It is not only simpler in overall structural composition and can reduce the overall weight, but also can be more convenient and faster in assembly and combination, and can have a more beautiful visual sense in the overall appearance. At the same time, it is easier for the user to wear and use it. It can be more anti-slip and comfortable, and has more practical functional properties in its overall implementation and use.

However, the pad system of the previous patent is made of thermoplastic rubber elastomer, and the pad body is integrally formed and injected to cover the lens, which not only makes the overall appearance more beautiful, but also improves the performance of the lens during wearing and use. Zhongneng has anti-slip and comfortable effects. However, since the lens surface is quite smooth, especially after the lens surface is electroplated with a coating, the lens surface lacks capillary pores, making it difficult for the elastomer (pad body) to be integrated with the lens to cover and fix it. Therefore, when wearing glasses, the lens The elastomer can easily detach from the lens, especially once it detaches during work, there will be an industrial safety hazard.

Therefore, there is a new type of "glasses" patent case No. M619746 announced on November 11, 2010. It is disclosed that it includes a lens unit, a cushion unit, and a wearing unit. The mirror body unit includes two left and right lens parts spaced apart, a nose frame part integrally connected between the lens parts, and a mirror top integrally formed on the top edge of the lens parts and the nose frame part. The cushion unit is integrally injection-molded on the top of the mirror and the nose bridge of the mirror unit. The cushion unit is made of soft material and includes a soft frame that covers and combines the top of the mirror, and a soft frame made of The central part of the soft frame part extends downward and covers the nose pad part combined with the nose bridge part. The wearing unit is arranged on the left and right sides of the lens unit. In the glasses, the cushion unit is injection-molded on the lens unit, which can have a stable combination effect. The top of the mirror has a plurality of perforations spaced left and right and connected to the front and rear sides, and the soft frame portion has the same number of fillets as the perforations and filled in the perforations respectively. By filling the fillets in the through holes, they are tightly bonded to each other and will not fall off after being manufactured and formed, thereby achieving good bonding firmness.

However, the surface of the lens in the previous patent is also quite smooth. Especially after the lens surface is electroplated with a coating, the lens surface lacks capillary pores, which makes the bite force between the insert and the perforation poor, and it is easy to fall off, causing workmanship. It is dangerous to use, so it is still not ideal in use.

Therefore, in view of the poor bite force between the current lens and the pad body (elastomer), it has the above shortcomings. Therefore, this invention provides a lens and soft elastomer combination structure, which includes: a lens, the upper edge of which is provided with a joining portion, and at least one surface of the joining portion is designed to be a roughened surface; an elastomer, which is coated with The elastomer is integrated with the joint part by injection molding, and the surface of the joint part is provided with a roughened surface to increase the bite force, so that the elastomer and the joint part are fully integrated and tightly combined.

Both sides of the above-mentioned lens are respectively pivotally connected with a temple.

The above elastic system is made of soft thermoplastic elastomer material.

The above-mentioned connecting portion is provided with a plurality of continuously arranged openings.

The above-mentioned method uses the elastic body to tightly combine with the openings to enhance the bonding force, so that the elastic body firmly covers the connecting part.

The inner edge surface of the opening is also provided as the roughened surface.

The above-mentioned opening is designed to be dovetail-shaped, circular, rectangular or drop-shaped.

The elastic system extends integrally to the bottom of the lens to form a nose pad.

1. Because the surface of the joint part of the lens and the inner edge surface of the opening are both roughened, the bite force can be increased, so that the elastomer can be fully integrated with the joint part of the lens to avoid the elasticity. The body and lens separate and fall off.

2. Since the elastic system is integrally molded and injected to cover the joint part of the lenses, the overall structure of the combined glasses is simpler and the overall weight can be reduced. Therefore, the assembly and combination are more convenient and faster to achieve the best results. Best lightweight design. And the combination of elastomers of different shapes and colors makes the overall appearance of the glasses more beautiful and fashionable. Moreover, it has the functions of anti-slip, comfortable effect and good adhesion when the user wears it.

3. The elastomer can be tightly combined with the dovetail-shaped, circular, rectangular or drop-shaped openings to enhance the bonding force, so that the elastomer can more firmly cover the joint part of the lens.

4. Since the elastomer and the lens will not fall off and separate at will, work safety accidents caused by falling off can be avoided to ensure safety in use.
